Thebman712 so my 280x has hdmi 1.4 right? that does 4k at 30hz right Speedbird I'm pretty sure it does. The HDMI 1.4 specification, which allows for 3840x2160 video at up to 30 Hz, was released in 2008. Your 280x should support it.

Or maybe different DP standards but as far HDMI goes they both have 1.4.
